Which system is required to be connected to the critical branch of the emergency system in a health care facility?

In a health care facility, the nurse call system is required to be connected to the critical branch of the emergency system because it plays a crucial role in patient safety and communication during emergencies. The nurse call system allows patients to alert nursing staff for assistance, which is essential in critical situations where immediate action is necessary.

Connecting this system to the emergency power supply ensures that it remains operational even if there is a loss of normal power. This capability allows health care personnel to receive alerts and respond promptly, thus maintaining the safety and care of patients during emergencies, such as power outages or other crisis scenarios.

While emergency lighting, fire alarm systems, and HVAC systems are important for overall safety and operational efficiency, the nurse call system's direct impact on patient care makes it essential for connection to the critical branch of the emergency system in health care settings.
